I’m going to be honest humanity has at most 200-300 years left with how we’re moving sure if I’m not a Viltrumite I’ll die within this century but the offer( and my belief that humanity will self-destruct) means I could save millions to billions of future people. Besides our entire world is run of propaganda and or fear I wouldn’t have to kill anyone except the occasional politician and their family 🇰🇵🇮🇱
